I crashed my Bepop 2 and the rear left motor got BBB out of the screws. Nothing seemed to be broken. I got the motor to it’s place. When I start the drone, look at the app when the drone is connected to my phone, on the screen says motor error 11. When I look closely it says in app rear left motor stage error. Can anyone help me how to repair my drone. Do I need new motor or is there possibly sth else wrong. Than you for your help.
